Definitions

  • the invention relates to a rail vehicle, in particular a rail vehicle for regional and long-distance transport.
  • Rail vehicles for regional and long-distance transport are increasingly being equipped with drive or traction batteries and, if necessary, additional fuel cell systems to supply, in particular, a drive system of the rail vehicle. This enables the rail vehicles to be operated even in non-electrified sections of a route network and thus enables the rail vehicles previously used to be replaced with internal combustion engines.
  • the drive batteries are arranged across several cars due to their large volume and weight.
  • the drive batteries are connected to one another via electrical lines routed between the cars, and this connection can be separated, for example, via controllable switches. Due to the direct voltage of the drive batteries, which is typically greater than 1kV, these lines are referred to below as high-voltage lines.
  • line modules of different types of supply are guided along a coupling rod that mechanically couples adjacent cars, one of the line modules being used to transmit electrical energy.
  • a vehicle in particular a rail vehicle, is known in which a flexible high-voltage line is guided by means of a cable guide device in the area of a gap between coupled car bodies, the cable guide device having a plurality of guide elements that are mechanically coupled to one another.

  • the European patent application EP 3 626 509 A1 discloses a rail vehicle with at least a first and a second end car, wherein a mains converter arranged in the first end car feeds a first traction converter in the first end car via a first DC intermediate circuit and feeds a second traction converter in the second end car via a second DC intermediate circuit.
  • the object of the invention is to provide a rail vehicle which enables optimal use of the roof areas of wagons for the arrangement of components, in particular of the drive system of the rail vehicle. This task is solved by the rail vehicle with the features of the independent patent claim.
  • the rail vehicle according to the invention comprises at least two cars, with car ends of adjacent cars being supported on a common Jakobs bogie, and an electric drive system, with the drive system having at least two drive batteries which are arranged on different cars, and wherein the drive batteries are connected via at least one high-voltage line are.
  • the rail vehicle is characterized by the fact that a section of the at least one high-voltage line is routed over the Jakobs bogie.
  • Jakobs bogies are often used in multiple units for regional and long-distance transport. They have the advantage that neighboring wagons or their wagon bodies can be supported on a common bogie, so that a separate bogie does not have to be provided for each wagon and the total number of bogies in the trainset can be reduced. At the same time, the Jakobs bogie allows the cars to move relative to one another, such as occurs when cornering.
  • the rail vehicle according to the invention comprises, for example, two cars, both cars being designed as end cars with a respective driver's cab.
  • the cars are supported, for example, on a respective bogie, while in the area of the other end of the car, on which a car transition is provided, over which passengers can move between the passenger compartments of the two To be able to move the car, it is supported on a common Jakobs bogie.
  • the rail vehicle includes one or more middle cars in addition to the two end cars, both ends of the car are supported on a Jakobs bogie.
  • the Jakobs bogie can in principle be designed either as a running bogie, whose two sets of wheels are usually not driven, or as a driving bogie with at least one driven set of wheels.
  • the other bogies can be designed as running bogies or as driving bogies.
  • a wheelset usually comprises a rigid wheelset shaft with two wheels arranged on it in a rotationally fixed manner, which are supported on rails.
  • the electric drive system of the rail vehicle includes, in a known manner, at least a number of drive converters or traction converters as well as a plurality of traction motors or traction motors, which drive in drive bogies via a respective gearbox or directly a respective wheel set.
  • the drive system additionally comprises at least one current collector and, depending on the supply voltage, possibly additionally a transformer and a mains power converter.
  • the drive batteries are each arranged in an underfloor area of one of the cars.
  • the at least one high-voltage line connecting them can advantageously have a relatively short length.
  • the drive system further has at least two fuel cell systems arranged on different cars, each fuel cell system having at least one fuel cell stack and at least one fuel tank, and each of the fuel cell systems feeding at least one of the drive batteries with electrical energy.
  • the fuel cell systems are each arranged in a roof area of one of the cars.
  • the fuel tanks and containers in which the fuel cell stack(s) and their electrical auxiliary operations including, for example, cooling devices are arranged are preferably arranged in the roof area of the car, in particular so that escaping fuel, for example hydrogen, cannot pose a potential danger to passengers. Due to the routing according to the invention of the at least one high-voltage line via the Jakobs bogie, more space is advantageously made available in the roof area for arranging these components of the fuel cell systems.
  • the section of the at least one high-voltage line is terminated at a respective interface in a respective underfloor area of the adjacent cars.
  • the section of the at least one high-voltage line is terminated at a respective interface in the underfloor area of the car, so that it is routed from the interface in one car via the Jakobs bogie to the interface in the other car.
  • the section in the respective transition area from the bogie frame to the wagon has a supplementary length Mistake.
  • the section is guided centrally over the transitions, for example by fastening centrally or largely centrally to a cross member of the bogie frame and to the underfloor of the car, the fastening being carried out, for example, by means of a respective block clamp.
  • the section of the at least one high-voltage line is additionally protected against environmental influences exclusively in a respective transition area between the car.
  • Such supplementary protection for example against moisture, can be provided, for example, by means of a supplementary casing of the respective line section, which is completed on the respective block clamp on the bogie frame and the underfloor.
  • corresponding protection over the further length of the section in particular the length guided in the Jakobs bogie, is not provided in order to enable largely unhindered heat dissipation from the line.
  • the section of the at least one high-voltage line in the Jakobs bogie is at least predominantly guided along a longitudinal member of the bogie frame of the Jakobs bogie.
  • these can preferably be guided parallel or largely parallel along one longitudinal member of the bogie frame, although alternatively both can also be guided on different longitudinal members of the bogie frame.
  • the section of the at least one high-voltage line is at least partially guided opposite in the Jakobs bogie Low-voltage lines and / or arranged low-voltage components are electromagnetically shielded.
  • Such shielding against electromagnetic radiation can be achieved, for example, by means of a grounded structure made of an electrically conductive material, in particular a metal.
  • a grounded structure made of an electrically conductive material, in particular a metal.
  • Such a structure can be additionally designed to guide the high-voltage cables along the bogie frame.
  • Low-voltage components that need to be protected include speed sensors and acceleration sensors.
  • the bogie frame of the Jakobs bogie is designed to be internal, with the longitudinal beams being arranged between the wheels of a respective wheelset.

  • the cars are constructed symmetrically and the components are arranged at the same locations on the car bodies WK.
  • the respective drive device has a traction converter TSR, which is arranged in the underfloor area UB of the car body WK. This is supplied with electrical energy by a drive battery AB, which is also arranged in the underfloor area UB, and supplies, for example, traction motors arranged in the motor bogie TDG of the car EW1, EW2, which drive the wheel sets directly or via a gearbox.
